The "SYM-1HCMG" is a half unit with a mixing monitor for a rear-insertion mixing distributor chassis compatible with 1GHz. It is half the height of conventional models and can accommodate up to 12 units in a 1UNHR chassis. The inter-terminal coupling loss is high performance, exceeding 30dB (over 25dB from 770MHz to 1GHz). Additionally, a version that typically supports up to 770MHz is also available in the same model. 【Features】 ■ 1GHz compatible ■ With monitor ■ Half the height of conventional models ■ Can accommodate up to 12 units in a 1UNHR chassis ■ A version that typically supports up to 770MHz is also available in the same model *For more details, please refer to the PDF document or feel free to contact us.

The "STFM-3WSPR" is a signal processor that receives FM signals, amplifies them, adjusts their levels, and removes unwanted signals. Both input and output are variable, allowing for the selection of any channel. The power supply is redundant, so by inputting from a separate power line, you can use it with peace of mind. Additionally, we also offer the frequency-fixed "STFM-1WSPR." 【Features】 ■ Frequency variable type ■ Receives FM signals, amplifies them, adjusts levels, and removes unwanted signals ■ Capable of selecting any channel ■ Redundant power supply ■ Can be used with peace of mind by inputting from a separate power line *For more details, please refer to the PDF document or feel free to contact us.

The "STSW-21WJR" is an RF signal automatic switch that inputs RF signals from antennas, transmission lines, etc., into two systems: main and sub. When the detection level on the main side drops below a specified threshold, it automatically switches to the sub side. It is equipped with an AUTO/MANUAL button, allowing for manual switching as well. The power supply is redundant, and by inputting from a separate power line, you can use it with peace of mind. 【Features】 ■ Output with operating contacts ■ Redundant power supply ■ Automatically switches back to the main side when the level on the main side returns to the specified threshold ■ Equipped with an AUTO/MANUAL button for manual switching ■ Can be used safely by inputting from a separate power line *For more details, please refer to the PDF document or feel free to contact us.

The "SMDY-1UNHR" is a chassis that accommodates mixed/distribution half-units compatible with multi-node systems. By significantly increasing the number of units that can be housed compared to conventional products, it is suitable for system diversification. Additionally, the chassis allows for flexible combinations of mixed/distribution units. 【Features】 ■ 1U subrack ■ Universal type ■ Accommodates mixed/distribution half-units compatible with multi-node systems ■ Significantly increased number of units that can be housed compared to conventional products ■ The chassis allows for flexible combinations of mixed/distribution units *For more details, please refer to the PDF document or feel free to contact us.

The "STJB-1" is a device that automatically resets and restores power without the need for human intervention when a circuit breaker is tripped due to lightning surges or overcurrent anomalies in CATV transmission lines, surveillance cameras, and unmanned base station facilities. Traditionally, personnel had to be dispatched to manually reset the tripped breaker, which took time to restore power. However, by installing this product, the restoration time is significantly reduced. Additionally, it is equipped with a function that outputs contacts when the breaker is tripped, allowing for easy monitoring by connecting to separate monitoring devices. 【Features】 ■ Automatic reset when the breaker is tripped ■ Significantly reduced restoration time ■ Equipped with a function that outputs contacts when the breaker is tripped ■ Easy monitoring by connecting to separate monitoring devices ■ Can be shipped in the main unit only or stored in a plastic box or stainless steel box *For more details, please refer to the PDF document or feel free to contact us.

Our "STSW-21WR" is an RF signal switch that inputs RF signals from antennas, transmission lines, etc., into two main/sub systems and allows for manual switching of the RF signals. The power supply is redundant, and by inputting from a separate power line, you can use it with peace of mind. 【Specifications】 ■ Transmission frequency range (MHz): 10–770 ■ Input/output impedance (Ω): 75F type ■ Input/output VSWR: 1.5 or less ■ Insertion loss (dB): A input within 3.5 / B input within 3.5 ■ Input monitor (A/B) (dB): -10 ± 2.0 or less, etc. *For more details, please download the PDF or feel free to contact us.
